Unable to build project I am using support library version 25.3.1

After adding helpstack library getting following issue while making build

Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.

com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/LICENSE

In packaging options exclude like below:
packagingOptions {
exclude 'META-INF/LICENSE'
}
then it will work
